Some business funding is offered with a personal guarantee, some without. It depends on the funder, the product, the amount and your trading history, and it is entirely the funder’s call.
Where a guarantee applies, it will be in the funder’s documentation, not hidden. Read that section before you sign, and ask the funder directly what it covers and for how long. Capvant does not sign anything on your behalf and does not hold any guarantee.
If a guarantee is not something you are willing to give, say so early. It narrows the set of workable offers rather than ending the conversation.
